I've had/have both. Will soon hit 5000 miles on the original BB30 bearings. Regreased the bearings at @3K miles and that took 10 minutes. To me, that's virtually no maintenance. If the crank bolt is properly torqued then there no no reason on this earth they should wear out fast. However, if it's too tight it's easy to see how they would wear out. No, BB30 requires no more maintenance, IF one knows what they're doing.
